hmm - this option is helpful:

  -core             toggles forced core dumps on fatal errors (off)

# Unix ONLY:
# If NO_FORCED_CORE_DUMP is set to TRUE, Lynx will not force
# core dumps via abort() calls on fatal errors or assert()
# calls to check potentially fatal errors.  The compilation
# default normally is FALSE, and can be changed here.  The
# compilation or configuration default can be toggled via
# the -core command line switch.
# Note that this setting cannot be used to prevent core dumps
# with certainty.  If this is important, means provided by the
# operating system or kernel should be used.

(I don't see a clean way to disable the signal handlers).
